Slim LED package
Disclosed herein is a slim LED package. The slim LED package includes first and second lead frames separated from each other, a chip mounting recess formed on one upper surface region of the first lead frame by reducing a thickness of the one upper surface region below other upper surface regions of the first lead frame, an LED chip mounted on a bottom surface of the chip mounting recess and connected with the second lead frame via a bonding wire, and a transparent encapsulation material protecting the LED chip while supporting the first and second lead frames.
1. A light emitting diode (LED) package comprising:
a first lead frame and a second lead frame spaced apart from each other;
an LED chip disposed on a surface of the first lead frame and electrically connected with the second lead frame; and
a resin covering at least a part of the surface of the first and second lead frames,
wherein:
at least one of the first and second lead frames comprises a groove which is formed thereon, and the resin is formed in the groove; and
the groove comprises a plurality of sub-grooves, each sub-groove having a triangular cross-section.
2. The LED package of claim 1 , wherein the groove is formed on an upper or lower surface of at least one of the first and second lead frames.
3. The LED package of claim 1 , wherein the first lead frame and the second lead frame have opposite sides facing each other, and at least one of the opposite sides comprises a depression formed thereon.
4. The LED package of claim 3 , wherein the depression is positioned on a lower portion of the opposite sides.
5. The LED package of claim 3 , wherein the opposite sides comprise slanted parts facing each other in a slanted state.
6. The LED package of claim 1 , further comprising:
a chip mounting recess formed on an upper surface region of the first lead frame,
wherein the LED chip is disposed on the chip mounting recess.
7. The LED package of claim 6 , further comprising:
an inner resin covered by the resin encapsulating the LED chip.
8. The LED package of claim 7 , further comprising:
a phosphor disposed in at least one of the resin or the inner resin.
9. The LED package of claim 8 , wherein the inner resin is disposed in the chip mounting recess.
10. The LED package of claim 9 , further comprising a phosphor disposed in at least one of the resin or the inner resin.
11. The LED package of claim 1 , wherein the resin is formed by transfer molding.
12. The LED package of claim 1 , wherein the sub-grooves are formed on upper surfaces of the first lead frame and the second lead frame.
13. A light emitting diode (LED) package comprising:
a first lead frame and a second lead frame spaced apart from each other;
an LED chip disposed on a surface of the first lead frame and electrically connected with the second lead frame;
a resin covering at least a part of the surface of the first and second lead frames;
a chip mounting recess formed on a upper surface region of the first lead frame;
a bonding recess formed in a upper surface region of the second lead frame; and
a bonding wire,
wherein:
at least one of the first and second lead frames comprises a groove which is formed thereon, and the resin is formed in the groove;
the LED chip is disposed in the chip mounting recess; and
a thickness of the second lead frame in the upper surface region is less than the thickness of the second lead frame in the other upper surface regions, and one end of the bonding wire is electrically connected with the second lead frame in the bonding recess.
